SPECIFICATION forming part of Letters Patent No. 223,817, dated January 27,1880.

Application filed November 24, 1879.

To all whom it may concern: I

Be it known that 1, JOHN RUSSELL, of Plattsburg, in the county of Clinton and State of Missouri, have invented certain new and useful Improvements in Pitman-Oonnections; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to certain improvements in pitman-connections. It is especially intended for use with machines which are suspended by or supported upon springs and have reciprocating horizontal movement as they are actuated by crank or eccentric and pitman.

Its object is to provide means whereby the pitman may maintain proper connection with such a machine while the latter works at different horizontal inclinations, and also adjust the tension of the supporting or suspending sprlngs.

My invention consists in certain details in construction and combinations-of parts, as will hereinafter be described, and pointed out in the claims.

Referring to the drawings, Figure 1 is a view, in side elevation, representing the in- .vention applied as in use. Fig. 2 is a perspective view of the invention detached from any machine. Fig. 3 is a vertical transverse 3 5 section of the preceding figure.

The machine to which this invention is applicable may be of any suitable construction, and adapted for any desired purpose, the form of connecting machine shown in the drawings 40 being merely for illustration.

Secured to the bottom of a swinging frame, A, is a hanger, B, whose horizontal upper portion is provided with transverse slots a. Boltsb fit in. said slots, and thereby permit the hanger to be laterally adjusted on the bottom of the swinging frame. In this way the pitman may be maintained in true line with its connecting-wrist on the actuating rotary Shaft.

A face-plate, O, is secured to the depending 5o portion of the hanger in vertical rotary adjustment, one or more circular slots, 0, being formed in the face-plate, in which fit correspondingscrew-clampsd. Thescrew-threaded extremities of these clamps engage with the hanger and maintain the face-plate in desired rotary adjustment thereon; hence the swinging frame may be vertically adjusted on its springs to work at different horizontal inclinations, and the pitmans throw be undisturbed.

Grooved lugs 0 project from the facet-plate and are provided with set-screws f. The pitman D is thereby adapted to have its working length adjusted bybeing moved in said grooved lugs into desired position, and then clamped therein. This adjusts the tension of the springs on which the swinging frame is suspended or supported.

Different changes and mechanical modifications may be made in the construction shown, and it is not considered necessary to specify them, as the following claims are drawn to broadly cover the principle of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters. Patent, is-

1. The combination, with a swinging or reciprocating frame upheld or supported by suitable springs, and having a hanger attached thereto, of a rotary adjustable faceplate provided with means for its adjustable attachment to a pitman, substantially as set forth.

2. The combination, with a swinging or reciprocating frame and a hanger secured thereto in a laterally-adjustable manner, of a rotary adjustable face plate pivoted to the hanger, said face-plate provided with one or more perforated lugs and set-screws for securing the face-plate to the pitman in any desired longitudinal adjustment, substantially as set forth.

3. The combination, with a swinging or reciprocating frame or receptacle upheld or supported by suitable springs, and having a hanger attached thereto, of a pivoted faceplate provided with arc-shaped slots and setscrews or clamps for securing said face-plate have hereunto set my hand this l2thday of in any desired rotary adjustment, said face- November, 1879. plate also provided with perforated lugs and set-screws for securing the face-plate to the O RUSSELL 5 pitman-in any desired longitudinal adjust- Witnesses:

ment, substantially as set forth. D. H. LINDSAY,

In testimony that I claim the foregoing I 1 GEO. R. RILEY.
